Arrange the following steps regarding HIV infection in correct sequence
A. Viral RNA produced by the infected cell
B. Virus infects macrophages.
C. Viral DNA is produced by reverse transcriptase.
D. Viral RNA is introduced into the cell.
E. Viral DNA incorporates into the host genome.
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → B, D, C, E, A
HIV first enters macrophages (B); its RNA genome enters the cell (D); reverse transcriptase makes viral DNA (C); the viral DNA joins the host genome (E); the infected cell then produces viral RNA and new virus particles (A).

NCERT Extract:
AIDS – “… After getting into the body of the person, the virus enters into macrophages where RNA genome of the virus replicates to form viral DNA with the help of the enzyme reverse transcriptase. This viral DNA gets incorporated into host cell’s DNA and directs the infected cells to produce virus particles (Figure 7.6).”
